What foods can you eat after you have a heart stent?

we are throwing a surprise party for my grandma. i am making this a new question since no one bothered to answer the other one about throwing a surprise party for her. this is for her birthday and her get better party, kind of like a 2 in 1. what foods can she eat that won't spike her blood pressure up and make her heart beat fast? she just had surgery for a heart stent. also, what should we do for the surprise party like stuff that you can order such as nice plates or silverware or just something that is valuable or some nice things and a theme we could have or preferably something not listed above that would be fun and cool. i would greatly appreciate it. nothing mean please!
